Please Help - Artifacts when booting / GPU-Z and Driver don't recognizes it

New Member

Hi guys, I have two GTX 480, water cooled. Well, I flashed them to the new bios, released in the end of 2010, I think it was released a few weeks before the GTX 580 launch, I did that looking for better stability and maybe a little of performance boost.

The strange thing is that after a few weeks, one day I used my computer for a few hours with the 480s at stock clocks, and I turned off my computer. The other day I turned on my computer and it was showing a lot of artifacts while botting, and my OS/Nvidia Control Panel/GPU-z dont recognizes my video card anymore and I can't change my screen resolution.
This is happening only with one card, the other is fine, no problem at all. I flashed my bad card to the original bios and I don't had any sucess, I tried with a lot of bios too. One more thing, the bad card it is my primary card.

What it can be? Dead card? If it was dead it is not supose to don't send video signal ?

I will spend more than 200 USD only in shipping, dont worth it. Using -4 -5 -6 at nvflash it will clean everything and then change it to the new file, right? I will try more flashes and if I have no lucky again I think I will try GTX 570 and 580 bios, LOL.

Thanks for the reply, like I said before I don't think RMA worth for my case, I will need to pay something around 230 USD with shipping. I will try gtx 570 and 580 and go back to 480 , I don't know, just 2 min to test and I don't have any other idea.

Cooking the card sometimes get it back to life, but I read that It will not long to much, is it true?

I have to admit, I was a little silly and very sleepy setting up an H2o rig at 1:00a.m in the morning and had an accident with a GTX 295 a £355.00 graphic card. I got a little H2o inbetween the waterblock and the PSB, the very next day I completed the system that I had been in a hurry to assemble and test; low and behold That card went "POP" I tryed to convince myself that I had not been carless and had that lump in my throat when I realised just what had happened.

Getting back to the point BAKING you need a very hot oven most won't cut the mustard; I learnt that day that Baking a graphic card in your own oven is not a good idea.

If you do have to do it; just to say you tried everything (before popping your $400.00 card in the bin). Make sure you remove all the plastic lables, serial numbers heatsink from the PSB first you will require an oven that will go as high as 285-290*F (pre-heated oven) to allow the solder to run ; place the PSB with the flat side down on grease proof paper and keep a careful eye on it, in the oven between 8-10 minutes max (8 minutes should do it); leave the oven to cool with the card inside do not attempt to move it straite after the baking process; make sure your kitchen is well ventilated.
(Please do more research on this subject online before you attempt it)

nb: expect the taste of hot PSB to be in your food for weeks, needless to say I leave baking to people that make bread these days.

My mentor Dr Robb (doctorate in real time computing) once said "as a profesional time is money and if you start to tilt the balance spending more time fixing; some times you have to cut your losses and stop fixing"

nb: don't forget to take a break from fixing and play some games, you still have a great card
